f304c6a7d4 refactor: apply new utilities and constants across codebase
P0 fixes:
- KV Cache migration: security.ts now delegates to kv-cache.ts (74% code reduction)
- Environment validation: index.ts validates env on first request
- Type safety: optimistic-lock.ts removes `as any` with proper interface

P1 improvements:
- Constants applied to deposit-agent.ts (TRANSACTION_STATUS, TRANSACTION_TYPE)
- Constants applied to callback-handler.ts (CALLBACK_PREFIXES)
- Constants applied to domain-tool.ts (MESSAGE_MARKERS)

40447952a9 refactor: migrate webhook to Hono router with auth middleware
webhook.ts:
- Convert handleWebhook() to Hono router pattern
- Create telegramAuth middleware with security validations:
  - HTTP method validation (POST only)
  - Content-Type validation (application/json)
  - Timing-safe secret token comparison
  - Timestamp validation (5-min replay attack prevention)
  - Request body structure validation
- Always return 200 to Telegram (prevents retry storms)
- Structured logging with context

index.ts:
- Import webhookRouter instead of handleWebhook
- Use app.route('/webhook', webhookRouter)

Benefits:
- Consistent Hono pattern across all routes
- Reusable auth middleware
- Better separation of concerns
